ORIGINAL: YourhandMyAss As far as I understand gastric bypass only cuts your stomach to a tiny little pouch so you can't eat very much, So if it's all about not eating very much, why can't you do that with out the surgury. I guess aside from not feeling full from normal size stomach and eating tiny amounts. The old version of this surgery (Vertical Banded Gastroplasty) and the current Lap Band surgery are just ways of making the stomach smaller. The most effective weight surgery, though, is called 'duodenal switch', and includes making a smaller stomach pouch, but also actually redirects food entering the intestines, so that it skips all but about a foot of the small intestine, which is the major absorptive portion of the intestines. The major risk with this surgery, beyond the operative time and recovery, is that so much of the small intestine is bypassed that there are risks of severe (even deadly) nutritional deficiencies. The next most effective version of the surgery (and one that doesn't have the dangers of malnutrition that come with the duodenal switch) is the gastric bypass. This surgery makes a small pouch in the stomach, and separates the remaining stomach completely. Then, the stomach is separated from the intestines above the duodenum, and attached further down the small intestine, but it leaves several feet of small intestine, so there is a much lower risk of absorptive issues and nutritional deficiencies. Being fat (fat enough to get one of these surgeries) may become a vicious cycle for some people -- especially people entering middle age. Because they are very large, it is difficult to exercise without damaging themselves. Without more exercise, they can't get their metabolism up high enough to lose weight, or they damage themselves trying to exercise. Damage causes them to be able to exercise less, so their weight increases OR dieting without exercising slows their metabolism even more, so they end up needing to eat less to maintain their current weight, and eating their normal amount causes them to actually gain even more weight. The trick is not to get on the treadmill of starving oneself to lose weight in the first place -- but unfortunately, 2-3 generations have been given crappy advice already, so slowing the freight train down until people get the message is going to result in a lot more people doing stupid stuff to try to contain their weight.
